VISIBLE OIL comranaa 7 Leonard Hyatt'and George Delbert Robbins,

A San Antonio, Tex. v .I Applicationoctober 5, 1934, Serial No. 747,086 i y v Y 1 claim. (ores-14) This invention is a device through the medium of which the conditioner the oil in the crank case may, by a garage or station attendant, be shown to a customer in a practical and visible mannerlf' I The invention comprehends the provisionpffa device which, after removal of the oil level gauge with which internal combustion engines, used in automobiles, are equipped, a sufiicient amount of oil may be drawn from thecrank'case and Figure 1 is an elevational view of the device embodying the features of the'present invention.

Figure 2 is a similar view taken at right angles to Figure 1.

Figure 3 is an enlarged detail sectional view throughthe device certain parts being shown in elevation.

Figure 4 is a sectional view taken substantially on the line H of Figure 1.

Figure 5 is aperspective view of a glass tube.

Figure 6 is a side elevational view of a second form of the invention.

Figure 7 is a front elevational view of the second form of the invention.

Figure 8 is a detail view taken substantially on the line 88 of Figure 7.

Figure 9 is a fragmentary detail view showing one manner of connecting one'end of the bulbequipped tube with a tube for insertion into the crankcase.

Figure 10 is a front elevational view of a third form of the invention.

Figure 11 is a detail view taken substantially on the line "-4 I of Figure 10. I I Figure 12 is a side elevational view of the third form of the invention.

Figure 13 shows anotheriorm of connectionbetween the bulb-equipped tube and the-tube insertable into the crank case.

Referring to the drawings by reference numerals, it will be seen that the device comprises an elongated tube ID of glass or other transparent material reduced in diameter at the end Illathereof. A bulb II has the largest end of the Figure "3, The'tube l3 maybe and effective manner.

tube Ill-inserted in the neck-of the bulb as clearly shown in Figure 3; r

A tube 12 of a diameter substantially equal to the'diameter of the end l0 of tube ll'l'is also provided and this'tube I2 is bent'as" shown, and 5,

.maybe and preferably is metal; being-adapted forinser'tion intothe crank'caseafterthe usual,

1 oil level gauge has beenremoved. A coupling sleeve l3 of rubber receives therein the end H! of the tube l0 and one end of the tube llin a 10: manner to connect the j tubes and as shown in v of suitable flexible material; preferably rubber. I

I A tubular receptacle of glass or other suitable material is secured to the tube l0 in spaced 15 parallelism to the'tube through the medium of clamps I5. The clamps l5 may be of: any suitable construction, and in the present instance-the clamps are each-iormed from a single strap of metal adapted to be disposed around the tube l0 and receptacle M with the ends of the straps connected" together through the medium ofu'a bolt l6 which also engages an intermediate portion of the strap in a manner to draw the encircling portions tight about the tube l0 and receptacle M as is thought apparent.

The receptacle I4 is divided into five sections through the medium of spacer disks l1 arranged therein as shown in Figure 3. In one of the sections, preferably the lowermost section, there is contained oil I8 which is unfit for use and which clearly shows the foreign matter therein. The remaining four sections formed by the disks I! are filled with new or clean oil IQ of different grades and as shown in Figure 3.

In operation, when it is desired to compare the oil in the crank case with the oils l8 and l9 7 in the tube or receptacle I4, the usual oil level gauge is removed from the crank case after I which the tube I2 is inserted into the crank case. 40

By pressing on the bulb H to collapse the same and then releasing the bulb,'obviously oil will be drawn from the crank case through the tube l2 into the sight tube In. Upon removal of the tube l2 from the crank case, the oil drawn into the tube Ill may be readily compared with the oils l8 and It! thus enabling the attendant as well as the customer to ascertain the condition of the oil in the crankcase in a quick, eflicient,

. After such a test or comparisomthe ofl in the tube) may be returned to the crank case and the device cleansed with gasoline or other suitable fluid.

In the form of the invention shown in Figures 6 to 8 inclusive, and also in the form of the invention shown in Figures 10 to 12 inclusive, instead of using a single receptacle it, two such receptacles are used. In the form of the invention shown in Figures 6 to 8 inclusive, these receptacles indicated by the, reference numeral Ha. I

are placed at one side of the tube Illa in intimate contact and are secured in position through the medium of spaced clamps I50. which, as shown, are each iormedirom a single strap of metal disposed about the receptacles Ila and the tube Illa in a manner clearly shown in Figure 8, with V the ends oi the straps connected together through the medium of a bolt l6a which-also en-- gages an intermediate portion of the strap in a manner to draw the encircling portions tight about the tube Illa and receptacles Ila in a manner thought apparent, the bolt lfia extend- -ing transversely through the tube Illa.

In the form of the invention shown in Flg-- of a suitable bolt lib.

The second and third forms of the invention will be usable at service stations which sell the oils of two or more separate companies.

If desired, instead of employing a metal tube,

' such as the tube l2 for insertion into the crank case, a rubber tube, pliable metal tube, or tube of any .other suitable material may be used; Where, for example, a rubber tube such as indicated by the reference numeral I: in Figure 9 is used, the reduced portion l0 0! the bulb-. equipped tube may be' suitably equipped with threads," so as to provide an efilcient conneclar make automobile.

tion between the bulb-equipped tube and the tube lib, or its equivalent.

Also, if desired, and as shown in Figure 13,

.- where a short rubber coupling such as the aforementioned coupling I3 is used, into the free end of the coupling may be inserted a suitable metdllic nipple 2| provided at its outer end with internal threads into which may be screwed the threaded end of a tube I20, and which tube, for insertion into the crank case, may be of rigid metal, and may be either straight or curved as found desirable and as required by the particufor theuse or the instrument in testing or comparing the crank case oil in all makes oi automobiles.

What is claimed is:

A device ior comparing crank case oil with other oils comprising an elongated cylindrical transparent tube having its lower end reduced, a bulb connected with its upper end, along tube connected with the reduced end and adapted to be inserted'in a crank case, whereby by pressing upon the bulb and then releasing the same, crank case oil will be drawn into the first mentioned tube, said tubes being permanently open excepting the end of the first tube closed by the bulb, and an elongated transparent receptacle oi less"length than the first tube, spaced clamps connecting intermediate portions 0! the receptacle with the intermediate portions of the first tube with the bottom of the receptacle located above the lower end or the large part of the first tube, and spaced transversely extending partitions in the receptacle dividing the same into a plurality'oi chambers for receiving used lubricating oil and different grades of new lubricating oil, with which the crank case oil in the first mentioned tube is to be compared the used oil beingplaced in the lower chamber.
